IMPALA-5881: Use native allocation while building catalog updates

This patch moves the allocation of thrift structures for serializing
the output of GetAllCatalogObjects() call into the native side. This
is done to prevent the Catalog from hitting JVM array limitations
(2GB maximum size) at scale. Additionally this patch also extends the
--compact_catalog_top=true to apply TCompactProtocol for the above
serialization to reduce the in-memory footprint.

This patch also caps the native allocations to not go beyond 4GB due
to Thrift library limitations. (Thrift internally uses uint32_t
datatype to represent the message size which limits the size to
~4.2GB).

Testing: Passed ASAN + HDFS core and DEBUG + HDFS exhaustive.

Deployed the patch on a 16 node cluster and tested it on a
Catalog-update topic of 3.5GB (uncompressed) or 780MB (compressed).
